Not sure why but human, feline and canines love my bed.
I will talk about the feline species first.
My sister, Ginger (who was the boss) use to fight with me over my bed. The deal is, she has to pin me down before I say yes and I always let her win.
Then she would snuggle up with me.
After she passed on, I thought "Great the bed is all mine" until my brother Pepper decided he was going to take over Ginger's place to keep me warm. I think it is called 'Sibling Bonding'
My friends Helios, Jack and Joey will tell you that Pepper has an identity crisis - he think he is a dog.
